(Cl. 20-54) Y 2 Claims. l

My invention as described herein, and illustrated in the accompanying drawings, consists of a window sash support, an object of which is to provide frictional means for holding a sash in raised position.

Another object of my invention is to provide spring controlled means for holding a sash tight against a parting strip.

A further object of this invention is to provide a spring controlled retainer strip for a window frame.

A primary object of my invention is the provision of means in a window frame for holding a sash tight against a parting strip, said means being also adapted to frictionally hold a sash in any raised position.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative .drawings in which:

Figure 1 is a vertical, sectional view of a window embracing my invention,

Figure 2 is a sectional view on line 2--2 thereof,

Figure 3 is an elevational view of the inner side of a retainer strip,

Figure 4 is an enlarged sectional view on line 4-4 of Figure 1,

Figure 5 is a transverse sectional view on line 5--5 of Figure 1,

Figure 6 is an enlarged sectional view on line 6 6 of Figure 1, and

Figure 7 is a detail of a cup.

While one embodiment of my invention is illustrated in the above referred to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in constuction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any way departing from the spirit and intention of my device, which is to be limited only in accordance with the appended claims. And While I have stated the primary field of utility of my invention it remains obvious that it may be employed in any other capacity wherein it may be found applica/ble.

In the accompanying drawings, and in the following specication, the same reference characters are used to designate the same parts and elements throughout and in which I0 refers to my invention and II indicates a window frame having a parting strip I2 for separating the sashes I3 and I4, the latter being slidable in a glyph or channel I5, formed by the strip I2 and a retainer strip I6. A conventional .blind strip and the parting strip I2 retain the sash I3 in the window frame. The strip I 6 is provided with several longitudinal slots I1, I8, and I9, in its rear wall 20, separated by walls ZI and 22, through which are bores. Strung through the slots and bores is a piano wire spring 24', the ends 25 and 26, of which are securedin the terminal bores 21 and 28 of the strip I6.

From the outer surface 29 of strip I6, are several horizontal relatively large .bores 30, 3| and 32, extending to the slots I1, I8, and I9, in which latter bores are seated countersunk cups 33, 34, and 35, each having a longitudinal horizontal slot 36. Projecting through bores 30, 3|, and 32, and slots I1, I8, and I9, and threaded into the wall 31, are screws 38, the heads of which seat within said cups 33, 34, and 35 and straddle the slots 36, whereby the strip is secured to the wall 31. All of the said screws pass to the outer side 4I of the spring 24, whereby the strip I6 will normally be spring pressed against the stile 42 of a window sash 43, thus at all times forcing the sash against the parting strip I2. The tension of the spring 24 is such that the sash I4 will be held in any raised position, but not such as to prevent moving the sash up and down. Stops 44 and 45, are attached to the lower end 41 of the wall 31, as well as the upper end of the same Wall to limit the in movement of the strip I6, when the upper or lower ends 48 and 49, of the strip are free, and cutouts 5Fl and 5I are provided in the upper and lower ends of the strips to receive the stops 44 and 45..

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the descrip-tion in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my invention, that which I claim as new and desire to procure by Letters Patent is:

i. The described device comprising a window frame, a parting strip therein and a movable retainer strip for a sash, .said retainer strip having countersunk cups embedded therein, slots in said cups and disposed transversely of said retainer strip, screws inserted through said slots and into said frame so that said retainer strip may move toward said sash, a longitudinal spring for urging the retainer strip against the sash, said spring being substantially coextensive in length with and carried within the retainer,l the ends of the spring being secured to said retainer strip and intermediate portions of said spring contacting said screws so that the spring is stressed, and means for limiting the movement of the retainer.

2. The described device comprising a window frame, a parting strip therein and a movable retainer strip for a sash, said retainer strip having countersunk cups embedded therein, slots in said cups and disposed transversely of said retainer strip, screws inserted through said slots and into said frame so that said retainer strip may move toward said sash, a longitudinal spring for urging the retainer strip against the sash, said spring being substantially coextensive in 4 length with and carried within the retainer, the ends of the spring being secured to said retainer strip and intermediate portions of said spring contacting said screws so that the spring is stressed.
